AREAS AFFECTED...THE CAROLINAS
CONCERNING...TORNADO WATCH 869...
VALID 271244Z - 271415Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 869 CONTINUES.
THE RISK FOR AN ISOLATED TORNADO CONTINUES TO EXIST THIS
MORNING...BUT IT IS NOT YET CERTAIN THAT A NEW WW WILL BE NEEDED AS
WW 869 EXPIRES AT 14Z.
THE STRONGER CORE OF THE 850 MB JET IS IN THE PROCESS OF MIGRATING
INTO THE NORTHEASTERN PERIPHERY OF THE BROAD/WEAKENING REMNANT
CIRCULATION ASSOCIATED WITH FAY...NOW OVER EASTERN TENNESSEE.
AND...LOW-LEVEL HODOGRAPHS ARE GENERALLY SHRINKING NEAR THE SURFACE
FRONT ACROSS THE CAROLINA PIEDMONT...WITH AN AREA OF STRONGER
MID-LEVEL ASCENT SHIFTING EAST OF THE CORRIDOR OF LINGERING MODEST
SOUTHERLY LOW-LEVEL FLOW...TOWARD MID ATLANTIC COASTAL AREAS. IT IS
POSSIBLE THAT GENERALLY LIGHT EASTERLY LOW- LEVEL FLOW VEERING TO
20-30 KT WEST SOUTHWESTERLY 500 MB FLOW ALONG FRONTAL ZONE ACROSS
THE COASTAL PLAIN OF NORTH CAROLINA COULD BE SUPPORTIVE OF WEAK
MID-LEVEL UPDRAFT ROTATION IN INCREASING SCATTERED CONVECTION
THROUGH MID/LATE MORNING. THUS...WHILE POTENTIAL FOR BRIEF/ISOLATED
TORNADOES IS PROBABLY LOW...IT MAY NOT BE COMPLETELY NEGLIGIBLE.
